Pokémon Pokopia uses Bulbasaur's Leafage as its example of adding greenery.
The game presents Ditto as a Pokémon that can befriend others and make use of their moves in the environment. Leafage is specifically associated with growing patches of grass, making it an early illustration of how Pokopia turns familiar abilities into creative tools.
This example is important because it shows the game's design philosophy: progress comes from restoring places and helping Pokémon, not only from defeating opponents. Players collect materials, build structures, grow vegetables, and improve habitats as they explore.
Leafage may be confused with other Grass-type moves from the broader Pokémon series, including Vine Whip and Razor Leaf. In Pokopia's documented gameplay example, however, the move used to add greenery is Leafage, supplied by Bulbasaur.
